Yeah i have already replaced it. The loose charcoal in my lines makes me think its the canister

I believe its probably that area, i use to smell it near the front but assume that was due to the EGR vacuum line that wasn't attached. i'll pull everything apart tomorrow and figure it all out

Hello, Been reading this forum since the day I picked up my 1997 Infiniti QX4 (pathfinder in a tuxedo) and have learned a great lot about the vehicle since and have already started some modifications and repairs. Vehicle mechanically seems really good and the body has next to no rust besides the side steps. Currently have an Auxbeam lightbar installed in the front grill, a roof basket with an extension and some Cooper AT/W's waiting to be put on. Decided ive posted enough to show off the new rig. This vehicle is primary a winter vehicle (not beater, more defeater ?) and hopefully will get to do some light/medium off roading.

Thanks for the heads up, I knew it was going bad as I have already cleared my lines in the engine bay of charcoal just need to clear the rest. Would you agree that with the canister failing it would explain why i occasionally smell gas?

Just thought I would update, fixing this did get rid of my P0400 code. still have the 1447 to figure out but one down at least, and for free

You sir rock. After feeling around forever i found it. Had to remove the valve, to be able to access it and assuming i put it back together all right (valve sits in a really short vacuum line/adapter) I should be good i hope!

Any follow up?

I hate check engine lights and I currently have one and have been working through the various codes. I have P0400 and P1447. I assume the 1447 is related to a bad charcoal canister as i cleared my lines of a lot of charcoal and i think for P0400 its due to either a stuck open EGR Valve or a bad EGRC solenoid. While working around in that area of the engine i found a vacuum line to nothing (attached image) and was wondering if anyone had the same or could show where it connects. I was looking on ProDemand and it shows on a diagram that it should T into other lines but i see no T and it's a short line that doesn't look broken or cut so i doubt it could reach that section anyways. Any and all help is greatly apprecieated

Okay, driving normally the transmission in D, lever in N, i can switch the auto mode on and it does a 50/50 torque split between the wheels when required, but stays RWD when not needed. At a stop, transmission in N, i can pull the lever back and engage 4L and see the light on the dash and lock auto enabled, and then swithc back to D. In all other scenarios i can push the lever a bit forward but not enough for it to engage anything or remain forward it just comes back to N (wigglin side to side) with no dash lights. My shift is Top H, Middle N (wiggle side to side), bottom 4L. engine is always running when attempting to switch. Here is a photo with the chart from Infiniti showing optimal settings and my shifter and such. There is a possibility N is the same as H and im just dumb but i dont think so? https://www.dropbox.com/s/91z835l54vogv86/Photo 2018-09-14%2C 3 32 42 PM.jpg?dl=0

I appreciate all of the info. In my case the problem is i physically cannot push the lever forward to engage H. I know the electric switch works because I can switch between 2WD and Auto and notice a physical difference.

First post and don't want to hijack the thread but how do you shift into 4H? I have a 1997 QX4 and have the opposite issue that i can stay and neutral and shift into 4L but cannot get into 4H
